Application filed July or, 1919. Serial No. 574.831.

To all whom it may concern Be it known that I, Ammo Ronny, a subject of the King of l-Iunga-ry, and residing at Berlin, Germany, have invented certain new and useful Improvements in Presses, of which the following is a specification.

. My invention relates to presses for making briquets, and a primary object is to provide a press, all the faces of whose mold are formed by movable stamps or rams which operate either together or in an optional order in succession. This pressure action on all sides enables the air to be removed from the briquet material particularly offectively.

{One special form of my invention is characterized by the displaceable or rotating mold table, which is Well-known per so, being employed as the bottom limiting face instead of the lower stamp being so employed, so that the briquet material can be preliminarily pressed in the mold which is formed exclusively by the stamps; the material preliminarily pressed in this manner is finally pressed in welhknown manner in the mold table itself after transference into a mold provided in known manner in the latter.

The press can be particularly advanta geously em loyed for briqueting coal. Namely, it as been found that the coal coming t'rom the drying chamber or store at a temperature of over 100 0., particle larly when it is in a loose condition, loses part of its capability of binding when it corres into contact wit' the open air before it is finally or at least preliminarily pressed.

' My invention afiiords the possibility of coal n u l lwinch is conveyed from thedrylng Cl'laHb.

ber directly into a suitably-shaped feed chamber being exposed to pressure on all sides without coming into contact with the open air;"it may here be a matter of pressing' the material preliminarily or .linally.

Another material advantage attaching to the subject-matter of my invention con sists in the same enabling perfectly dustfree pressure, so that the production of dust which is otherwise unavoidable in the case of various materials is im ossible.

Several illustrative em odiments of my invention are represented by way of example in the accompanying drawing, wherein Figure .1 is a vertical longitudinal section showing a press in which all the walls Fig. 2 is a vertical longitudinal section;

showing the parts in their position cit-ring the filling operation, Fig. 3 a horizintalsection in the plane li -B in Fig. 2, Jig. 4: shows the position of the parts when-fie preliminary pressing ope 'ation is complete and Fig. is a horizont'. section in plane CD in Fig. i. wnile Fig. 6 is a horizontal section showing another modified form of the movable walls.

Referring firstly to Fig. l, the material to be pressed is fed into a chamber a through the flanged tubular chute Z). When coal is being briqueted the chute b is connected directly with the drying chamber by a pipe. The walls of the chamber a are formed'so that six stamps or rams can move in the same, namely two vertical rams c,-

twdhorimntal rams 03 moving in the plane of the drawing and two rams 0 moving at right angles to this plane, and the ends of these rams form the walls of the mold. In thisillustrative embodiment the rams are of' rectangular section and the pressing laces thereof are plane; I may. however form them otherwise, for example .calotteshaped in which event the material is pressed for example into the form of a sphere.

The press illustrated in l. is'operated by material to loo-pressed. being fed intermittently or continuously through the chute I), while the stamps c, d, e siln 'taneously move outward and inward-end t. tiring the latter motion briquet the materiel which is located between their pressinlg' faces in the manner readily understood from Fig. l,

by employing the subject-matters o3? my Uni ted States patent applications Serial llos.

5023.783 and 508,784 filed July 531, 1909. In this event only the tour horizontal stamps d, e would at first move toward one another and preliminarily press the mater then the two vertical i (1 W0 operate, the horizontal stam'giis (Z, c. which are curely"'held in the meantime, actin as sliding molds. In order to do tl1lS, l1DW6V8l, the feed box or chamber a would have to be displaceable vertically with the stamps (i, c, which would necessitate the chute Z) being connected with a flexible pipe. The process described in my former applications referred to above could, however, also be employed it the v .tical walls of the feed box a were t'ormeo of several parts in such manner that one part can be displaced relatively to the others. instead of using the vertical stamps c, 0 for the mode oi. pressing described in the applications referred to above, one of the pairs of stamps (Z, (Z or e, a may be employed for the same purpose. The construction of the feed box a or its mounting would then have to be modified correspondingly.

in the illustrative embodiment according to Figs. 2 to 5 the subject-matter of my invention used in combination with a mold table 2', rotating in well-known manner, whose mold-- Z are alternately tilled and emptied agziin during one revolution of the table. The movable stamps f of the embodiment according to Figs. to act, in combination with the mold table 1', as a prelin'iinary press, while the real or final pressure is brought about by the ram h and the counter-ram 7a.

'lhe illustrative en'ibodiments shown in lies. 2 to 5 comprise only two horizontally displaceable preliminary pressure stamps f, whose operative faces 9 are formed semi-circular. so that these surfaces form a complete cylinder when the stamps contact one another, as shown in Fig-5. The operative faces 7 may, however, be made angular as shown in Fig. (3, so that when the stamps contact one another a die of square section is inclos-ed by the same.

The mode of operation of the illustrative embodiments according to Figs. 2 to 5 and Fi 6 is such that in the position according to dig. 2 the mold is filled. in the direction of the arrows. This fillingis brought about, for example, as in the illustrative embodiment shown in Fig. 1, by means of a closed receptacle a which may be connected with a drying chamber or the like. The two lateral rams f occupy the relative positions shown in Figs. 2 and 3 while thevert-ical ram It islocated in its uppermost position. The two rams f then approach one another until they occupy the position shown in Figs. 1 and during this time the mold table 2' has rotated so that its mold Z is located under the ram it and under the briquet mass surrounded by the rams f. lVhile the table is securely held the top stamp it presses the pre-' liminarily formed briquet from the mold ,7 into the mold Z, the stamp in acting as counterstan'ip. The arrangement may, however, be such that the rotating mold table 2' is omitted. T he top stamp it then becomes operative as soon as the rams f occupy the position shown in Figs. 1 and 5. The top face of the counter-ram here limits the bottom side of the mold g. The bottom stamp Z: may act in like manner as the pressing stamp proper, the top stamp it being formed as counter-stamp. Lastly, both stamps may operate simultaneously.

()hviou.--;ly, the brirpieting process disclosed in the applications referred to above may likewise be employed in connection with the illustrative embodiment shown in Figs. 2 to 5 and Fig. 6 both with and without the rotary mold table 2'.

Those stamps which are formed as preliminary pressure rams may be provided with perforations or duets opening into the atmosphere in order to accelerate the removal or" the air. In order to prevent these passages becoming stopped up pins may projectinto the same in such manner that when the rams, e. g. f, move outward these pins clean the passages.

I claim y 1. In a press of the type described, the combination of a feed chamber, and stamps movable in the walls of the chamber, the inner ends of the stamps in their innermost position forming a mold in the chamber, said stamps being adapted to move away from and toward one another.

2. In a press of the type described, the combination of a mold table, a feed chamber on the mold table, stamps movable in the alls of the chamber, the inner ends of the stamps in'their innermost position forming a preliminary mold in the chamber, atop vertical stamp movable in the top wall of the chamber, and a bottom stamp at the mold table, said stamps being adapted to move away from and toward one another.

3. In a press of the type described, the combination of a feed chamber. and stamps movable in the walls of the chamber, the inner ends of the stamps in their innermost position forming a mold in the chamber, said stamps being adapted to move away from and toward one another, said feed chamber being closed and supplying material. to be pressed to the mold termed by the stamps, atmospheric air being thereby excluded from the material.

In testimony whereof, I allix my signature in the presende of two witnesses.
